While creating Azure managed redis in West Europe Region, getting Request failed due to insufficient capacity. Retry using a different Azure Managed Redis size or region. (Code: InsufficientCapacity). Even tried different SKU sizes B0,B3 and B5.
Your suggestions are most welcome.

    Hello @Naphade, Ketan [EXTERNAL] ,

    The InsufficientCapacity error indicates that Azure is currently unable to allocate capacity for the requested Azure Managed Redis configuration in West Europe.

    Since you have already tried B0, B3, and B5 and received the same error, there is no need to keep retrying these sizes repeatedly.

    If your application allows it, please try deploying the Managed Redis instance in another supported Azure region. If West Europe is mandatory for your requirement, please raise an Azure Support request so that the Azure Managed Redis team can check the capacity availability for your required configuration in West Europe.

    When raising the support request, please include:

    • Region: West Europe
    • SKUs/sizes attempted: B0, B3, and B5
    • Complete InsufficientCapacity error
    • Failed deployment details and correlation ID from the Activity Log
